This datasource is a generic module to handle any information provided by an indicator.
This module will return either a serie of single data or a serie of array.
If the input arguments contains a string like ``Indicators::BOL/99'', we will assume that the user wants to have all data available form the Bollinger indicator and we will return an array with all the data.
If the input arguments contains a string like ``Indicators::BOL'' (It's the same than ``Indicators::BOL/0''), ``Indicators::BOL/1'' (or / any number), we will assume that the user only wants a serie of single data, which is in our example the third serie (keep in mind that the first serie start at zero).
We will either use only a single data serie or a all data available for the calculation of the value range.
